CABLE-CUTTING DEVICE.

H I Patented Get. 14, 1913.

. To all whom it may concern Be it known that 1, WILLIAM T. QUINLIN, acitizen of the United States, residing at Coalinga, in the county ofFresno and State of California, have invented certain new and usefulImprovements in Cable-Cutting Devices; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same. I

This invention relates to improvements in devices for cutting wirecables.

One object of the invention is to provide a device of this characterwhich is particularly adapted for cutting wire cables containing anumber of strands and which is designed to hold, the ends of thestrandsor wires in close compact form when out and to prevent any piecesof the wire from flying out and injuring the operator.

Another object is to provide a cable cutting device which may be appliedto a cable at any point between the ends thereof thus obviating thenecessity of insert ng the end ofthe cable through the device and whichwill make a clean out through the cable at one place only.

Wlth these and other objects in view, the invention consists of certainnovel features of construction; and the combination and arrangement ofparts as will be more fully described and claimed...

In the accompanyingl'd'rawings; Figure l is a side view of my improvedcable cutting device; Fig. 2 is an enlarged central verticallongitudinal section thereof; Fig. 3 is a top plan View of the lowersection or member of the devicefFig. i is a vertical cross sectionthereof taken on the line H of Fig. 2; Fig. 5 is a similar view taken onthe line 55 of Fig. 2; Fig. 6- is a similar view taken on the line 6- ofFig.2; Fig. 7' is a detail side view oft-he movable cutting bit of thedevice; Fig. 8 is a perspective view of the stationary cutting bit'ofthe device; Fig. 9 is a similar view" of the spring fior preventingthe rebounding-of the movable cutting bit when operated to-cut thecable;

Fig. 10 is a similar view of oneoi the combined clamping devicesand'h'an'dlesfof the device. I

My improved cable cutting device coniprises a body ortion consistin ofupper and lower menu are 1 and 2 in the; fermof substantially oblongmetal blocks. In the upper side of the lower member 2 of the block isformed a semi-circular groove 3 while in the lower side of the uppermember is a similarly disposed semi-circular groove 4. ,When the upperandlower members-o1- blocks 1 and 2 of the device are brought to getherin operative position the grooves 3 and 4 therein register and form acentral longitudinally disposed assage with which the cable is engagedat t e point where the latter is to be cut as clearly indicated in Fig.2 of the drawings. By constructing the body of the device in separablesections as herein shown and described it will be seen that the same maybe applied to a cable at any point in the length thereof thus ob-.

viating the necessity of inserting and drawing the cable throu h thedevice in order to reach the point .w ere the cable is to be severed.

When the members or blocks 1 and 2 of the device are'engaged with thecable in the manner described, said blocks are clamped together andsecurely fastened in operative engagement by combined clamping members'.an'd'handles 5 comprising rectangular framesjhavin'g therein suitablylocated cross bars 6 and having their lower sides formed I by theinwardly turned lower ends 7 of the vertical sides of the frame, saidin-.

Wardly turned ends terminating-a short distance from the sides of theframes and forming gripping lugs as clearly shown in Figs. 6 and 10 ofthe drawings. In the lower side ofthe lower member or block 2 of thedevice at the point where the clamping members are engaged therewith areformed transverse grooves 8 with which the endsof the lugs 7' of theclamping members 5 are engaged and by which said lugs are held inposition. a

The upper sides of the ends or the upper member 1 of the device arebeveled or inclined outwardly and downwardly as shown at 9 to facilitatethe engagement of the over the ends of the device. In swinging theclamping members inwardly over the beveled ends 9 of the device theforcible enagement of the cross bars with'said beve ed ends ofthe upperblock 1 will draw and v clamp the upper and lower blocks into tightengagement as will be readily understood. By leaving the lower sides ofthe clamping members 5 open or constructing said lower sides in the formof the lugs 7 it will be seen that the open space left between the lugswill permit the clamps to be let down over the cable at the ends of theblocks 1 and 2 so that said members may be readily engaged with the endsof the device Wherever the same is placed on the cable.

In the upper side of the lower member or block 2 of the device is formeda centrally disposed recess 10 adapted to receive the lower stationarycuttingbit 11 of the device, said bit comprising a block of hardenedsteel the lower portion of which is adapted to closely fit the recess'10 and the upper portion of which projects above the upper side of thelower block 2 and engages a recess 12 formed in the lower side of theupper block 1 as clearly shown in Figs. 2 and 4 of the drawing. upperportion of the bit 11 is formed a V- shaped notch 13 the walls of whichare beveled or inclined from the inner toward the outer side of the bitas shown at 14 thereby forming at the inner side of the block a sharpcuttin edge 15. Also'formed in the upper side of the lower block 2adjacentto and communicating with the recess 10 is a passage 16 which isof less width than the recess 12 and is adapted to receive the lower endof the movable cutting bit hereinafter described. The passage 16preferably extends entirely through the lower block, as shown.

In the upper block or member 1 adjacent to and communicating at itslower end with the recess 12 is a vertically disposed rectangularpassage 17 which extends entirely through the upper block 1 as shown.Slida'bly engaged with the passage 17 is a movable cutting bit 18comprising a hardened steel bar having a cross sectional shape corresending to the shape of the passage 17 an having a length greaterthan thethickness of the upper member 1 of the device. The lower end of the bit18 is curved and beveled as-at 19 to form a cutting edge 20 which isadapted to co-act with the cutting edges formed by the V-shaped notch inthe lower stationary bit/11. v

In one side of the bit 18 are formed a; series of ratchet teeth 21 withwhich are engaged the downwardly turned outer end of a spring pawl 22which is preferably in the form of a flat spring metal platehavingtherein near its outer end a rectangular slot 23 with. which isengaged a bolt 24 the inner.

end ofwhich is secured in theupper side of the upper member 1 of thedevice and with the upper end of which is engaged a clamp-v ingnut 25which when screwed down on the bolt securely clamps the slotted end ofthe pawl to the upper member 1 in such posi- In the projecting tion thatthe free end of the pawl engages the ratchet teeth 21 on the bit 18 andprevents the' latter from rebounding after be ing operated to cut thecable as will be hereinafter more fully described. By roviding the slot23 in the end of the paw the latter may he slipped back when the clamping nut is released thereby disengaging the outer end of the pawl fromthe ratchet teeth on the bit 18 to permit the latter to be retracted.

In the operation of my improved cutting device the upper and lowermembers thereof are engaged with the cables at the point where the sameis to be cut and when so engagedthe cable will lie in the V-shaped notchof the lower or stationary bit 11 as clearly, shown in Figs. 2, 1 and 5of the drawings. After the device has thus been applied to the cable andthe clamping members 5 adjusted to fasten the blocks 1 and 2 togetheraround the cable in the manner described, the movable cutting bit 18 isbroughtdown into forcible engagement with the cable by a blow from ahammer or other instrument. When thus forced downwardly the co-action ofthe cutting edge on the lower end of the bit 18 with the cutting edgesof the stationary bit 11 will sever and make a clean cut through thecable. The engagement of the spring pawl with the ratchet teeth 21 onthe bit 18 will positively prevent the bit from rebounding after beingstruck and will thus cause the bits to cut the cable at one point only,or in other words will prevent the blades from gashing or making aragged out, should it be necessary to impart a second blow to the bit.The ends of the cable or the strands thereof when out in the mannerdescribed will be confined and prevented from falling apart by the wallsof the passage formed by the grooves in the engaging sides of the upperand lower members of the device and will thus obviate any danger ofinjury to the' operator by the flying strands or particles of metalwhich frequently occurs in cutting woven or twisted wire cable in theusual manner.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to withoutdeparting from the principle orsacrificing any of the advantages of the invention as shown.
